The document discusses handedness and lefthandedness versus righthandedness. It notes that less than 10% of the population is lefthanded, and this percentage has remained unchanged. It asks why the human population is predominantly right-handed and discusses some disadvantages lefthanded people face, such as fresh ink smearing when writing left to right and non-optimal keyboard layouts. The conclusion is that what's most important is that both lefties and righties are together as one population.
